토착미생물과 첨가제를 이용한 음식물류 폐기물의 상온 발효 사료화 및 동물 사료로의 활용성 평가 (Fomentation of Food Waste Mixed with Additives by Indigenous Bacteria at Room Temperature and Utilization of Fermented Feed for Animal)

초록

In this study, manufacture of feedstuff using food waste was examined to estimate feasibility of utilization for animal. Rice bran and popped rice were used as bulking agent and soil containing indigenous bacteria was used as fermenting agent. Food waste including 40 ? 5% moisture content was fermented at atmospheric condition for 15 days. The results were compared with feedstuff without adding soil to examine effect of indigenous bacteria as a fermenting agent. When soil was added in food waste, it generally appeared higher temperature than that of food waste without soil. Also, pH was sharply decreased during high temperature because organic acid was generated. From the nutritional analysis, crude protein, crude fats, crude fiber and crude ash, calcium (Ca) and phosphorus (P) were sufficient content as fermented feedstuff. From the results of identification using 16s rDNA analysis, it can be confirmed that fermentation mechanism may be occurred by Bacillus subtilis, Paenibacillus polymyxa. In the analysis of harmful materials, heavy metals (As, Cd, Cr, Pb, Hg) and aflatoxin were in below in permission standards of feedstuff (korea) and salmonella was not detected. From the results of dog breeding experiment, F8 (fermented feedstuff) providing as feed showed the highest body weight and weight increment among F5, F8 and commercial feedstuff. The results revealed that food waste can be utilized as foodstuff in animal breeding instead of commercial feedstuff.
